How Schematics are Used in Electronics

Video Transcript

" Hello! This is Ross on behalf of the expertvillage.com. Schematics. All right. This is how we communicate. Just like a music. You put notes on piece of paper just like communicate your ideas or you need to communicate our electronic ideas or circuits and we use schematics that is the language of electronics and so I can put in a resistor, I can have a capacitor and if the capacitor is electrolytic or something has a polarity to it like this put a plus symbol on it. If it is a variable resistor I could do that make it a potentiometer, a diode, it is here. Or a light emitting diode I can just put some arrows on it. So there is this language of schematics. They represent the connections to each one of them. So what we will do for the garage well, we will talk about that later. You combine these. So in a schematic what we will do, let us say when you get power to the circuit and you go through the resistor you can go through a light emitting diode. You might even go out here to some other type of load may have a motor that you want to connect to, then it comes back and you can put a switch in here if you wanted to put it down here if you want to and so the circuit when it is open like it is shown no current can flow, let us close, current flows and you get the motor on and the light lights up."
